Abstract

In this work, the effect of pressure on the crystallization (Tc) and glass transition (Tg) temperatures of a modelled PdSi liquid alloy was investigated for different cooling rates by using Quantum Sutton Chen(K-SC) potential which is used to determine the interactions between atoms. It was determined that at the cooling rates of 2,5x1011 K/s and 2,5x1012 K/s the alloy system in liquid phase transformed into crystal and amorphous phase, respectively. The glass transition temperature was defined by the Wendt-Abraham parameter and radial distribution function (RDF) peaks. It was concluded that the increment of pressure led to an increase in the crystallization and glass transition temperatures and the ratio of Tg/Tm resulted in an improvement of the glass forming ability.

Özet

Bu çalışmada atomlar arasındaki etkileşmelerin belirlenmesinde Kuantum Sutton Chen (K-SC) potansiyel fonksiyonu kullanılarak farklı soğutma hızları için model PdSi sıvı alaşımının kristallenme (Tc) ve camsı geçiş sıcaklıklarına (Tg) basıncınetkisi incelendi. 2,5x1011 K/s ve 2,5x1012K/s soğutma hızlarında sıvı fazdaki alaşım sisteminin sırasıyla kristal ve amorf faza dönüştüğü tespit edildi. Camsı geçiş sıcaklığı Wendt-Abraham parametresi ve radyal dağılım fonksiyonu (RDF) piklerinden belirlendi. Basınç artışınınkristallenme, camsı geçiş sıcaklığıve Tg/Tm oranınıyükselterek camsı oluşum kabiliyetini arttırdığı tespit edildi.
